GEA supplies glass plant catalytic filter
GEA Glashütte Freital contracted with GEA for supply and
installation of a compact plant for the cleaning of flue gases resulting from
melting furnaces. ( More recently GEA announced that 2 meter candles are now
available for this technology) The Customer selected GEA’s BisCat technology
(Bischoff Catalysator technology) thanks to low space requirement and
combination of several process steps in one reactor. The new furnace has a
melting capacity about of 150 t/d, commissioning along with GEA’s emission
control plant was scheduled for March 2019.
Generally the furnaces in the glass production are equipped
with flue gas cleaning plants which have separate steps for treatment of
particulate, acid crude gases and nitrogen oxides. GEA has developed a
technology which reduces these steps to one single step in a single reactor. The
flue gas cleaning process is carried out by means of rigid filter elements
consisting of coated mineral fibers, so-called ceramic candle. These candles are
well-proven and very flexible to use even with regard to modifications of
operating parameters, especially at high gas temperatures. Even stricter future
requirements set in the Federal Administration‘s Regulation “Technical
Instructions on Air Quality Control (TA Luft)” will be under-run. Dust emissions
are near to detection limit.
GEA has already delivered plants of this kind for the purpose
of hot gas filtration and has now refined these plants recently in order to
include the separation of nitrogen oxides resulting from flue gases (DeNOx). The
ceramic candles are installed in a walk-in clean gas chamber to ensure easy
access for maintenance and inspection.
